Nestjs Patterns

This gives you production-ready NestJS patterns covering the full stack: module organization, DTO validation with class-validator, guards and interceptors, environment config validation, and testing setups that mirror your runtime pipes and filters. It pushes you toward thin controllers with business logic in services, consistent error envelopes, and validated config that fails fast at boot instead of at first request. The common folder structure and auth examples are immediately useful if you're past the tutorial phase and need to know where guards actually go or how to stop leaking password hashes in responses. Opinionated enough to save you from analysis paralysis on folder layout, but the patterns are standard NestJS rather than some custom framework.
